vertically concatenate struct values from the same field

Hi I encountered an issue in vertically concatenation of struct values from the same field. e.g. given S1

[S1(1:10).vals] = deal([1,2,3])

what I want to achieve is to extract all values from the field 'vals' of struct 'S1'. I could do it in a for loop so that

t= [];
for i = 1: 10
    t = [t;S1(i).vals];
end

Since such commands appears frequently, is there a neater code for this purposes using structfun?

Any suggestion would be appreciated!

V = vertcat(S1.vals)
V = vertcat(S1(1:10).vals)

Thanks! that's very neat. Also thanks for your supplementary materials. The comma seperated list looks powerful.
